   After lunch, the rest of the class returned and Griff noticed that all
three bullies were having trouble sitting still in their chairs, possibly
due to the discomfort of their deflowering, or perhaps from the strange
sensation of the remains of his semen dripping out of their formerly
virginal pussies into their underwear...probably both.  Once again, Griff
was confused and amazed that he could get away with punishing these
16-year-old students, first with spankings and then by fucking them raw and
possibly knocking them up.  He paused, losing himself in those memories,
and then looked up at Treena in the back row of the classroom.  A moment
later, he blinked and then recomposed himself enough to keep teaching.

   Ariel, Penelope, and Hadiza caused no further problems that afternoon.

   --

   After dinner, Griff was relaxing in his room when his door opened and
Treena and Penelope stepped in.  The juxtaposition of the tall blonde and
the slim, short, brown-haired girl was stark.

   He quickly sat up.  "What?!  You girls can't be in here!  How did you
unlock the door?"

   Treena closed it behind them.  "It was unlocked, just like I asked you
to leave it.  And don't worry, Mr.  Parr, nobody saw us."

   "You asked me to leave it unlocked?" Griff didn't remember that.

   "Mm hm.  Tell Penelope to get naked."

   "Um...Penelope, take off your clothes."

   The blonde beauty did as directed, though a little quicker than earlier
in the day, he noticed.  Griff saw that the nipples on her B-cup breasts
were hard.

   "C'mere..." he patted the bed next to him and Penelope lay down.  His
mouth went immediately to one of those hard nipples and she gasped at the
sensation.  His hand snaked down to rub between her legs but found that she
was already wet.

   Treena sat on the corner of the bed.  "Because three times in a row was
too much earlier, I asked the bullies when their periods last started. 
They're spread out so we can concentrate on one at a time, and Penelope's
ripe right now.  You might have even got 'er earlier today, but I want to
make sure."

   Griff pulled off of Penelope's nipple and looked down at the sexy
blonde's slim tummy.  Deep inside her, he knew, if it hadn't already been
fertilized, an egg was waiting for his sperm.  He shifted onto his back and
pulled off his own clothes.  "Roll on top of me, Penelope." The girl did
so, her eyes wide as she felt his hardness press up between her legs. 
Griff reached down and angled the tip of his cock so that it was lined up
with her no-longer-virginal pussy.  "Now slide down."

   The pretty blonde moaned as Griff's slim six incher wormed its way
inside her once again.  She pulled off a bit and then winced as she pushed
back down.  He hadn't told her to do that, but was pleasantly surprised. 
Soon she was riding him slowly, adjusting her body and movements to
maximize her own feelings of pleasure.

   "Huhh..."

   That breathy moan had come from the foot of the bed.  Griff looked over
but Treena was no longer there.  The room seemed darker than before, full
of shadows.  He didn't know where she had gone, but he had more important
things to concentrate on.  He reached forward to simultaneously manipulate
Penelope's clit while squeezing one of her breasts.

   "Oh!" Penelope gasped and he felt her pussy grip him in orgasm.  He was
glad for all the orgasms he'd had hours ago or he would have lost it right
there.  He backed off to let her ride it out and remembered that she had
been the only girl to cum earlier too.  When her breathing slowed, he began
to thrust up into her.

   "Please, Mr.  Parr...unh...please..." she moaned.

   Griff brought her face to his and kissed her.

   "Mmph!" Penelope was moving upon him under her own power again.  After
they tongue wrassled for a bit, she broke the kiss.  "Please...don't..."
But her body was moving faster upon him, at odds with her words.  "...I
don't...don't want a...auhh...a babyyyy!" She arched her back, her head
angled upward, her mouth open.  "Aiiee..."

   As before, the cries she made were quiet, muted like a TV turned way
down so as to not disturb Griff's sleeping parents while his teen self
watched the porn channel.  He felt the girl's insides squeeze him again,
her primed body nursing at his penis until he could hold back no more.  He
grunted as his orgasm blew through his loins and his seed rushed up his
cock.  "Unhh!" he cried out as he inseminated the fertile young woman once
again, his dangerous sperm penetrating her forbidden, unprotected depths.

   "M-huhh!" she gasped as her orgasm extended from the sensation of her
vulnerable reproductive system being inundated by her teacher's hot,
sperm-filled semen.  "Auhh!" Her body shook in pleasure, the unfamiliar
sensations overwhelming her even as her defenseless womb betrayed her,
spasming open to allow Griff's seed access to her most intimate, private
place once more.

   "Nng!  Huhh!"

   That gasping had come from the foot of the bed again.  Griff rolled the
still-shaking Penelope off of him and blinked.  One moment there was no one
there and the next, Treena was laying there, her skirt gathered at her
midsection and her hands in her underwear as she pleasured herself to her
own release.

   "What...what...?" Griff stammered.

   Treena looked over at him.  "Huh?  Oh...I lost concentration." She
quickly pulled her skirt down as she sat up.

   "But what just happened?"

   "Forget about it." Treena looked at him intently and Griff felt that
pressure again.

   "Forget about what?" he asked.

   "Exactly."

   --

   Every day for the next few days, Treena got herself, Griff, and Penelope
together in a private place, whether his room, the girls' change room, or
their classroom after the rest of the students were dismissed.  There, he
inseminated the gorgeous blonde again and again while Treena watched and
got herself off at the thought of the 16-year-old bully getting knocked up
by her teacher.

   The next night, Treena brought Hadiza to his room.  The voluptuous Black
girl removed her clothing without being prompted by either Treena or Griff
and got onto her hands and knees on his bed.  "Yess..." she moaned as Griff
speared his thin six incher inside her.

   Griff reached around and molested the girl's C-cup breasts as he took
her hard.  She was the shortest of the bullies, so he felt his cock bottom
out inside her on his deepest thrusts.  As he continued to fuck the
dark-skinned young woman, he looked over at Treena.  Over the last few days
the thin girl had been less shy about jilling herself while he fucked one
of her bullies.  The brown-haired girl's panties were off and Griff could
see her slipping her fingers inside her wet pussy.

   She noticed him looking and blushed.  "Shouldn't you be focusing on
Hadiza, Mr.  Parr?"

   He just kept staring at Treena as he plowed into her antagonist.

   Treena nibbled her lower lip.  "Do you...prefer my body?  You said you
liked teen girls.  The teenier the better, maybe?" She splayed her slim
legs and used her fingers to spread her vagina open for his inspection.

   "Hungh!" Griff groaned and blasted Hadiza's unprotected insides.

   Hadiza, already on edge from the vigorous fucking, moaned, "Yes..." and
started cumming herself as she felt her teacher's hot, dangerous sperm
penetrate her vulnerable depths.  "Uhh!  Uhh!" The head of Griff's cock
bounced off of her cervix as it spasmed in pleasure, causing some of his
seed to slip inside her ready womb.

   The trysts with Treena and Hadiza continued for the rest of the week. 
Treena became more bold in her masturbation, lying right next to Hadiza as
Griff inseminated her bully.  Griff knew at a core level that he shouldn't
try to touch Treena without her permission, though.

   --

   After class the next day, Griff headed to the library, though he
couldn't say why.  He walked right by Paula the librarian, who seemed not
to notice him, before heading through a fire door and down a hallway.  He
pushed open a wooden door to find just Treena, laying on a makeshift bed of
cushions and blankets in a book storage room.  "No Hadiza?" he asked as he
closed the door behind him.

   "No, she's not fertile anymore, and Ariel won't be ready for a few more
days.  Lay down."

   He lay next to her.

   "You've been so good, Mr.  Parr, so I'm gonna lighten up on you a little
so you can ask some questions."

   He immediately felt slight relief from a pressure in his head that he
hadn't even realized had been there and blinked at his renewed clarity. 
"I...Treena...how have you been doing this?  What I've been doing to those
girls..."

   "Did you ever listen to that old radio serial, The Shadow?" she asked
him.

   "Uh, no."

   "Well, there are some recordings of it in the library archives.  He was
a man who had the power to 'cloud men's minds', making himself invisible
and even influencing others' thoughts.  Last year, I found that I could do
that as well.  After some...trial and error...I figured out my limitations.
I could affect the minds of those who liked me, or wanted to help me, but
with people who didn't, I needed to put in a lot of effort, and I couldn't
do much to the strong-willed ones.  So even with my 'super power' I
couldn't stop the bullies, especially Ariel and Penelope." She sighed. 
"The teachers want to help students, so they were receptive.  I tried to
get Ms.  Ferguson to kick those three out of school, but she was overruled
by the board.  They have rich parents."

   She put her hand on his chest.  "Then I figured it out: I needed a
handsome male teacher, one who those girls would respect and be attracted
to, and when you told Ms.  Ferguson that you liked teen girls, well, I knew
that you were perfect!  I could use those girls' unconscious desire to
please you, piggybacking my power onto that and making it so they couldn't
resist your commands.  I didn't really plan much beyond just shutting down
their bullying, but when you suggested spanking them?  Brilliant."

   Griff gulped.  "Treena, this will come out...I'll be fired..."

   "Ah ah ah, enough of that."

   He felt the pressure in his head increase again.

   She looked into his eyes.  "I'll let you remember this conversation, but
I'm putting a command in your head that you can't tell any of the students
or teachers...nobody outside of the school either.  And don't worry so
much, okay?" Her eyes flashed with delight.  "You're getting what you want:
to fuck hot teen girls.  Speaking of which..." She unfastened the top two
buttons on her shirt.  "I'm not gonna force you, but do you want me?" She
looked up at him with those big pale blue eyes and held her breath.

   Griff moved forward and kissed her, making her squeal into his mouth. 
He had pretty much just been concentrating on her every time he fucked
Hadiza, the voluptuous student just being too womanly in comparison with
this cute little thing.  As they French kissed, he unfastened the rest of
the buttons on her shirt before pulling back to regard her chest.

   Treena nibbled her lower lip as she waited to see how Mr.  Parr would
react to the sight of her little bra over top of her A-cups.  He smiled and
brought his mouth to one of her pointy little nipples, visible through the
fabric, and she squealed again.  "Tickly!  Ohh..." He had lightly gripped a
nipple between his teeth through her bra and that felt better.  With her
concerns alleviated, she couldn't stop talking as he helped remove her
clothes, "I'm 16 but my body doesn't seem as developed as other girls my
age, maybe because of my special ability?  But you like it, don't you, Mr.
Parr?"

   "Mmm..." Griff agreed as he reached around to unfasten Treena's bra.  He
hummed again at seeing her puffy pale pink nipples.  Grabbing her hips, he
pulled her yellow panties down, leaving her completely naked except for her
white school socks.  Because he was already between her legs, he dove his
face into her downy crotch.

   "Ah-hahh..." she moaned as he slipped his tongue inside her tight little
pussy.  "Oh woww..."

   Griff noticed that her clit had come out to play and lapped at it while
his hands moved up to squeeze her small boobies.

   "Ohh!  I...unhh...I...OHH!" Treena arched her back as she came from the
intense stimulation.

   Griff felt the taste of her pussy juice on his tongue before he slipped
it back inside her.

   "Still?" she moaned.  "No, too much...ohh..." Her core remained taut
from that orgasm as her pleasure ramped up once more.  As Griff pinched her
nipples, she came again.  "NNHH!  Huhh!  Ahh..."

   "Hopefully that's enough lubrication," Griff commented as he freed his
cock from his pants and slid up between her legs.  He eased the head
between her very wet pussy lips and pushed gently but insistently.

   Treena stared at her teacher's penis as it slowly slid into her virginal
passage.  Even though Mr.  Parr's member was slim, it still seemed crazy
that something that size could fit inside her little body.  There was a
strange feeling of pressure and then a sharp pinch.  "OH!" She wrapped her
arms and legs around him.  "Hold...still...just a sec..."

   Griff did so and waited.  He could feel Treena's vagina pulsing, her
body trying to expel the foreign invader, but he knew that was just
reflexive.  A minute later, he felt her relax and her legs fell back to the
cushions.

   "Okay, keep going."

   He pushed inside a little more, pulled back, and then repeated.  He was
halfway inside her now.  He could feel her working on her breathing, and on
the next soft thrust he was 3/4 of the way in.  After a couple more, he was
fully embedded in the nubile young woman's formerly virginal pussy.

   "Oh...my...God..." she moaned.  "I feel like you're splitting me in
half."

   "I'm glad I'm not that thick, or this probably wouldn't have worked at
all," Griff responded before he started to lightly thrust.  Treena panted
as she felt his shaft slowly slide back and forth inside her.  The
discomfort of her deflowering was already gone, replaced by the novel feel
of his member moving where she had never been touched before.  Then he
started to pick up speed.

   "Kiss me..." she moaned, and he did.  His movements were getting faster
now, aided by the lubrication being produced by her increasing pleasure
level.  She felt him reach down to grab her little butt, holding it tightly
so that he could grind against her, stimulating her clit once more.

   "HHH!" she cried out into his mouth as she came again.  Unlike when he
had been going down on her, though, this time her internal muscles were
surrounding six inches of hard cock, making her orgasm more intense. 
"MMM!"

   He broke the kiss.  "Treena, I gotta pull out..."

   She felt him withdrawing and wrapped herself around him.  "No!  Unh! 
Inside!  Insiiidde..." Her orgasm was calming down but she knew what she
wanted.

   Griff couldn't pull out.  "UNHH!" he grunted and thrust hard inside the
young woman to deposit his seed as deep as possible.  "UNGH!"

   "Yeess..." Treena moaned as she felt her insides melt from his hot lava
and came again.  "NGH!  A-hh!"

   Spurt after spurt of Griff's cum injected itself almost directly into
the girl's womb as her cervix spasmed open and closed around the tip of his
ejaculating cock.  Both lovers gasped at the incredible pleasure of their
forbidden coupling.

   Then their mutual orgasm was over and Griff carefully withdrew, causing
Treena to gasp.  She had just gotten used to the sensation of her teacher's
hot flesh inside her.

   "Shit, Treena, when was your last period?"

   She sighed.  "It's kind of random...sometimes it arrives on time and
sometimes it doesn't come for months.  Hell, once a couple showed up 2
weeks apart!  I think my last one was 6 weeks ago?  It's
embarrassing...that's why I got so mad at them for the red ink prank."

   As he moved back up to hug her tiny form, his half-hard penis bumped
into her pudendum.

   "Nope!" she responded.  "I'm feeling really sore now, so no more until
tomorrow, mister."

   "Aww..."

   --

   The next night, Treena came to Griff's room, unconcerned about getting
caught due to her ability to cloud others' minds.  Once again, Griff filled
her tight teenage pussy with a load of his boys before she went back to her
own room, walking funny but utterly satisfied.

   The next day, at lunch, she had him order Ariel to stick around while he
leisurely fucked Treena on his desk.  After she came twice and him once,
Ariel was forced to suck him back to life.  Then Treena made the redhead
lick her clit while the smaller girl bounced on Griff's cock in the reverse
cowgirl position while he sat in his chair.  When he was ready to cum,
Treena quickly dismounted and shoved Ariel's face forward, forcing her
bully to swallow her teacher's load.  Afterward, Treena smiled as Ariel
tried to cough out one of the spurts that had gone down the wrong pipe.

   To be continued...
